Specification of Letters Patent.

ratenteol April 17,1906.

Application filed January 3. 1905. Serial No. 239527.

To all whom it may concern:

- Be it known that I, MARoUs D. W001), a citizen of the United States, residing at Centralia, in the county of Lewis, in the State of Washington, have invented certain new and useful Improvements in Harness-Snaps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification. I

My invention relates to improvements in harness-snaps.

The object of my present invention is to provide a cheap, simple, efficient, and reliable harness snap so constructed and arranged as to avoid the necessity for the use of any kind of springs to secure its holding engagement with the parts with which it is con.- nected.

My invention relates to an improvement in harness-snaps and is embodied in the construction and arrangement of the parts pres ently to be described, and defined in the claims.

The principal novel features of my invention are the means for obviating the neces sity for employing the usual spring; and it consists in the cooperative relation between the slotted shackle and the pivotally-mount ed and slotted interlocking hook having a saddle portion adapted to aid in securing the parts in a normal position when in use.

,Similar reference-numerals indicate like parts throughout both views, in which Figure 1 is a side view of my invention, partly in vertical section, to show the relative arrangement of the interlocking parts. Fig. 2 is a plan view of the same, showing the parts in their normal position.

All parts of my invention are preferably made of suitable metal and of any proper dimensions.

The shackle 1 has its bifurcated outer end provided with a fixed or integral cross-bar 2, to which that portion of the harness on which my invention is employed is properly secured in the usual or other proper manner. The forward end of this shackle is pro vided with a fixed or integral tongue 3, provided upon its outer end with a locking-lug 5, adapted for a holding engagement with the cooperating hook in the manner hereinafter described.- The forward end of this tongue 3 also preferably has a recess 4, Fig. 1. The inner end of this tongue has an oblique slot 8, Fig. 1, a horizontal plane face 6, and an adjacent oblique face 7, all for the purpose about to be described.

The hook 9 has an inner curve 14 and has its rear portion provided with a longitudinal vertical slot 10 adapted to receive the said tongue 3 .of the shackle and is pivotally secured thereto by means of the pin, rivet, or bolt 13, which passes loosely through the slot 8 and is adapted for a free play therein. The inner end of this hook also has a saddle portion 12, which bridges over the inner end of the slot 10 and is adapted to normally rest upon the horizontal face 6 of the shackle, but is adapted to rest upon the oblique face 7 when the hook is open, as shown in dotted. lines in Fig. 1. The forward end of this hook has a longitudinal vertical slot 11, adapted to loosely admit and contain the locking-lug 5 and to normally form a secure holding engagement therewith, as shown in Fig. 1.

The operation and manner of employing my invention thus described is obvious and, briefly stated, is as follows: When the shackle 1 is secured to that portion of the harness upon which it is employed in the usual manner, the parts of my invention will be in the relative position shown in full lines in Figs. 1 and 2, with the lug 5 in a holding engagement in the slot 11 and the pin 13 at the forward and lower end of the slot 8. When it is desired to free the hook 9 from its engagement, it can readily be done by lifting upward upon the free end of the hook into the position shown by dotted outline in Fig. 1, after which it can be conveniently engaged with the bridle-ring or other desired portion of the harness and then as readily replaced in its normal position. When the hook 9 is in its raised position, the saddle 12 rests upon the oblique face 7 of the shackle, and when it is in its normal position the saddle rests upon the face 6.

It is obvious that the oblique slot 8 permits a limited longitudinal play of the hook 9 and at the same time aids in maintaining the parts in their locked position in use, and since the strain is normally exerted longitudinally it is obvious that the principal strain is upon the pin 13 instead. of upon the locking-lug or the face 6 of the tongue 3.

My improved harness-snap is thus simple, convenient, and reliable and does away completely with the usual unreliable spring.

Having thus described my invention, What I desire to secure by Letters Patent is A harness snap consisting of a shackle whose end is adapted for attachment to the harness, and Whose other end has a tongue having an oblique guiding-slot near its inner end and provided upon its outer end With an interlocking lug, and a hook mounted in said oblique slot and having a longitudinal verti-
